Abstract: A generally thin, flexible sanitary napkin capable of absorbing medium to high menstrual flows, and having a stiffened center is provided. In one embodiment, the sanitary napkin has a longitudinal central region disposed along the length of at least a portion of the longitudinal centerline, and longitudinal side regions are disposed outboard of the longitudinal central region. The longitudinal central region of the sanitary napkin has a flexure-resistance that is greater than that of the longitudinal side regions. The embodiment of the sanitary napkin described above easily forms around the curvature of the wearer's labia majora by cupping and surrounding the exterior of the labia majora. The longitudinal central region of the sanitary napkin forms the bottom of a cup-like trough under the wearer's labia majora, and the longitudinal side regions are sufficently flexible that they are able to form the sides of the trough structure.

Abstract: A system for normalizing measurement obtained from spectrometers to correct for measurement biases in individual spectrometers. The normalization system is adapted for use in spectrometers having an optical assembly for obtaining characteristic data from a test sample. A normalization factor is obtained in each spectrometer by placing a holographic dispersion filter between the light source and detector in the position normally occupied by the test sample, the filter having been encoded with a symbol representing a nominal value of light expected to pass through the filter. The spectrometer a determines the value of light passing through the filter and calculates a normalization factor based on the ratio between the nominal value of the filter and the actual value obtained by the spectrometer. The normalization factor is stored in system memory and the filter removed so that the spectrometer may thereafter be used toevaluate a plurality of test samples. The measured results obtained from the test samples are normalized by multiplying them by the stored normalization factor. Where measurements are obtained from a plurality of spectrometers, the normalized results vary less than about 10% from instrument to instrument for a variety of types ofcharacteristic data, including turbidimetric microalbumin assays.

Title: Generateur electrique thermodependant et procede correspondant

Granted: 2005-10-18
Abstract: Concernant la génération thermodépendante de courants de référence, on s'intéresse la plupart du temps à la génération de tensions de référence plutôt qu'à la génération d'intensités de référence. Dans certaines applications telles que les diodes de commande des lasers, ce sont des intensités dont on a besoin plutôt que des tensions. La présente invention vise ainsi à remplacer les références en tension par des références en intensité. On peut ainsi considérer que la logique de mise en oeuvre est l'inverse de celle utilisée selon l'état antérieur de la technique. La thermodépendance des intensités étant connue, le procédé consiste à traiter les intensités (1, 2) selon un processus linéaire et/ou non linéaire de façon à générer des intensités (3) caractérisées par des compensations de température définies. L'avantage de l'invention est directement que le produit scalaire et l'addition (ou la soustraction) sont plus faciles et plus simples dans le domaine des intensités que dans celui des tensions.

Abstract: A synchronous discontinuous transmission medium access control (SDTX-MAC) method and apparatus for more efficiently using existing uplink channels by sharing these uplink channels between multiple terminals engaged in bursty data transmission. This is accomplished by assigning each mobile terminal an individual time slot and by not requiring each mobile terminal to broadcast its identity. This results in a reduction in the number of receivers on each base station and a reduction in the length of the synchronization message.

Abstract: An architecture and method for fast precharge of bitlines in a densely packed, dynamic content addressable memory is disclosed. The dynamic content addressable memory cells are arranged according to an open bitline architecture to obtain high packing density. The bitlines are precharged through equalization between every two adjacent open bitline pairs. More specifically, a bitline and its adjacent neighbouring bitline on the same side of the bitline sense amplifiers are equalized at several locations along the bitlines such that they are equalized at high speed, which is typically not available in open bitline architectures. Hence the adjacent bitlines are precharged in a manner similar to a folded bitline architecture. Additional equalization circuits are connected between the complementary bitlines of each open bitline pair, therefore during the precharge phase, all four bitlines of the two open bitline pairs are equalized with each other. To ensure that all four bitlines equalize to the midpoint voltage level, complementary logic levels are written to the bitlines prior to equalization.
